I have this exact same copy of the Red Book (from 2006) and wanted to ask whether it would still be relevant (compared to 2016 book), or if there would be some serious discrepancies that would render it invalid today. I had the 2016 book, but I gave it away to a friend. I understand the price list would be slightly different- with inflation, but would anything else be different? Opinions would be much appreciated.
Don't use books. Instead, use pcgscoinfacts.com. They have ALL the coins and all the grades possible with real auction price results. To get the latest and most accurate price estimates, I average all the prices the coin has gone for, and that will be the latest average price that the average collector will pay for a normal untoned coin with no errors or anything else. If you still plan on using your 2006 Red Book, don't. Prices for certain coins have sky-rocketed because all of a sudden there are none left, or some of them have plummeted after a collection of a million of these rare coins has been found (just making up examples of course)
Every collector should have a Red Book handy. Great tool for quick information. Nothing wrong with a 2006 edition.
I agree that every collector should have a copy of the Red Book. It's so much more than a price guide. It contains information that can't be found in any other single book.
The only problem with using a 2006 Redbook is the pricing data. The rest of the info like weights, montages, basic grading guidelines of circulated coins, and the historical info is still accurate. Even regarding the pricing sections, you can still get an idea if your coin is a common date or better date when compared too others in that series I usually get a new copy every 5 years or so. But if I want to look up mintages or weights I just grab a random edition of shelf
